Abstract
Lung ultrasonography has a tailored diagnostic and therapeutic approach in the critical care setting. Lung ultrasonography in critically ill (LUCI) is a helpful modality for the early detection and assessment of various lung pathologies and guides the management protocol for the same. The aim of this review was to highlight the basics of an ultrasound machine, the fundamentals of a lung ultrasound and the importance of lung artifacts in detecting the anatomy and pathology of the lung disease. In addition, we have also discussed regarding the effective approach to lung ultrasonography through the two protocols: the Bedside Lung Ultrasound in Emergency (BLUE) protocol and the Fluid Administration Limited by Lung Sonography (FALLS) protocol.
